To all whom, t may concern:

Be itJ known that I. ROBERT N. ADAMS, a'citizen of the United States, residing at Richfield, in the county of Sevier, State of Utah, have invented certain new and useful Improvements in Beet-Harvesters; and I do hereby declare the follow-ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use `the same.

This invention relates to beet harvesting machines.

*A The object of the invention resides in the provision of a beet harvesting machine embodying an improved construction. of topping mechanism. v With the above and othereobjects the inv vention consists in the detail of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters lof referhas been adjusted upwardly to its'full extent; Fig. 4, a view similar to Fig. 2 showing all the parts of the machine at the limit of their upward adjustment; Fig. 5, a front view of the machine; Fig. 6, a section on the` line 6-6 of Fig. 2; Fig. 7,1:a detail perspective view of a portion of the forward end of the machine; Fig. .8, a section on the line 8-8 of Fig. 7

Referring to the drawings the-machine is shown as comprising a main frame A which includes front and rear members 10 and 11,

side members 12 and 13l and intermediate 'longitudinal members 14 fand 15. Supported upon the intermediate longitudinal members 14 and 15 is a forward cross beam 16 and a rear cross beam 17 and upon these cross beams 16 and 17 is mounted a` draft l tongue 18 and an operators seat 19. Mounted `on the'y side member 13 and the intermediate longitudinal member 15 are vertiypose that will hereinafter appear.

cal frames 20 and 21 respectivelywhich are provided with internal teeth 22 on one side. Also mounted on the side member 12 and intermediate longitudinal member 14 are vertical frames 23 and 24 respectively which are also provided with internal teeth 25 on one side. Disposed between the frames 20 and 21 is a shaft 26 which has fixed on its ends pinions 27 and 28, the pinion 27 meshing with the teeth 22 of the. frame 20 and the pinion 28 meshing with the teeth 22 of the frame 21.l Also fixed upon the shaft 26 Just inwardly of the pinion 27 is a worm wheel 29 which is inclosed by a casing 30 loosely mounted upon the shaft 26. Also inclosed by the casing 30 is a worm 31 meshing with the worm wheel 29 and having secured thereto a stem 32 rotatably mounted in a bearing 33 pivoted upon the `rear member l1 of the frame A and terminating in a crank lhandle 34 whereby said stem may be rotated to eii'ect the rotation of the worm 31. By this construction it will be apparent that yby rotating the stem 32 the shaft 21S-will also be rotated to move said shaft up and down as a result of the engagement yof the pinions 27 and 28 with the teeth 22 of the frames 20 and 21 respectively.

Loosely mounted on the shaft 26 is a traction wheel 35 which has secured to the inner side thereof a sprocket wheel 36 for a 113m'- 1sposed between the frames 23 and 24 is a shaft 37 which has xed on the ends thereof respectively pinions 38 which mesh with the teeth 25 of the frames 23 and 24 respectively. Fixed on the shaft 37 just inwardly of the frame 23 is a worm wheel 38 surrounded by a casing 39 loosely mounted -on the shaft 37. The casing 39 also incloses a worm 40 which meshes with the worm wheel 38- and has attached theretoy a stem 41 rotatably mounted in a pivoted bearing 42 mounted on the rear member 11 of the frame A. The end of 4the stem 41 remote from the worm 40 terminates in a crank handle 43 whereby the rotation of said stem may be conveniently effected. By this construction it will be apparent that upon the rotation of the stem 41- the shaft 37 may be raised and lowered. Loosely mounted on the shaft 37 is a traction wheel 44 which has fixed thereto a sprocket wheel 45 for a purpose that will presently appear. Pivoted to the inner side of the intermediate longitudinal member 15 at the rear end of said member is one end of a beam 45', while a corresponding beam 46 has one end pivoted to the inner side of the intermediate longitudinal member 14 atthe inner end of said longitudinal member. Secured to the forward ends ofthe beams 45 and 46Vare plow beams 47 and 48 respectively which carry on their forward ends plows or diggers 49. Secured to these diggers 49 respec- Itively are rearwardly directed rods 50 for a pur ose that will hereinafter appear.

' ounted upon the beams 45- and 46 respectively are bracketsv 51 in which are rotatably mounted the ends of a shaft 52.

Fixed upon this shaft 52 are spaced sprcket'iwheels 53 and 54 which Valine with sprocket wheels 55 and 56l respectively fixed upon a shaft 57 rotatably mounted in brackets 58 extending rearwardly from and secured to the rear member 11 of the frame A. Traveling upon the sprocket wheels 53, 54, 55 and 56 is an endless conveyer 59 'cfa construction suitable for elevating the beets delivered thereto from the diggers 49. Jour* naled on the intermediate longitudinal member 15 and the side member 13 is a shaft 60 which hasy loosely mounted thereon a 'sprocket wheel 61 adapted to be connected to the V"shaft 60 by a clutchelement 62 normally held active Yby a spring 63 and `controlled throughl suitable connections 64 with a hand 'i lever-65'mounted upon the longitudinal intermediate member l5. Traveling on the f sprocket wheels 36 and 61 is a sprocket chain 66 and fixed on the outer end of the shaft 60 is a gear 67 which meshes with a gear 68 fixed 'on the shaft 57. By this construction it will b'e'apparent that when the machine is moved along the ground andy the clutch element 62 thrown in the shaft 57 will be rotated--to efe'ct'the operation of the conveyor 59. i l

J ournaled upon the tongue 18 just forward of the front member 10 of the frame A is a transverse shaft 69 which has secured thereto one end of a lever 70 whereby said shaft may be rotated. The shaft 69 is provided withvcrank arms 71 and. 72 which are connected at their free ends to the arms 73 and 74 respectively "of a U-shaped yoke which embraces thetongue 18.l The arms 73 and 74 of this yoke are also connected ad- "jacent their free ends to the beams 48 and 47 of the diggers 49. By this construction it will lbe apparent `that upon rotating the shaft 69 the diggersl 49 can be' raised and ylowered and likewise the receiving end of p from the front member 10 of the frame A are spaced brackets 84 and 85 which support a rod 86. Pivotally mounted on this rod S6 are the inner ends of beams 87 and 88, the outer ends of said beamsbeingsecured respectively to the inner ends of the vertical arms 79 and 81. Depending from the horizontal arm 78 of the angle member B are brackets 89 and 90 in which are pivotally mounted respectively the forward ends of arms 91 and 92. The inner ends of these arms 91 and '92 are curved upwardly and slidably engaged through guides 93 mounted on the inner sides of the beams 87 and 88'respectively.

Secured to the free ends of the arms 91 and 92 are the corresponding ends of leaf springs 94 and 95 respectively, the other ends of said springs being secured between the horizontal arms 78 and 80 of the angle members B and C. The springs 94 and 95 Vthe arms 99 and attheir upper ends against the arms 91v and 92 respectively. Mounted on'one of the arms 99 is` a horizontal rod 101 which extends diagonally across the machine at the rear of the knives 98 so as to vthrow the beet tops severed by the knives to yone side. Connecting the arms 99 is a fender respectively which have journaled on their' lower ends cultivating disks 105 and 106 for the purpose of throwing the soil away from the rows of beets as the machine moves along the ground.

Journaled on the clevis frame 76 is a transverse-shaft 107 which has fined thereon a toothed roller 108 and a sprocket wheel 109, the latter being connected to the spocket wheel 45 by a sprocket chain 110. By this construction it will be apparent that as the machine moves along the ground the roller 108 will be rotated to force the beets rearwardly 'on the lrods 50 to effect the proper delivery thereof to .the endless conveyer 59. Mounted on the forward end of the tongue' 18 is a bracket 111 upon which is matinee pivoted a lever 112. One end of this lever is connected to the clevis frame 7 6 by a link 113 so that by manipulating the lever 112 the topping mechanism which includes the knives 98 and cultivators 105 and 106 can be raised and lowered to meet the particular conditions at hand.

What I claim is 1. In a beet harvesting machine the combination of a wheeled frame, a pair of arms pivoted on said frame, spring means yieldingly supporting the free ends of said arms, a stemmounted on each arm, and a circular knife rotatably naountedv on the lower end of each stem, said knives being disposed in the same horizontal. plane and coperating to sever the beet tops passing' therebetween.

2. Ina beet harvesting machine the combination of a wheeled frame, a. pair of arms pivoted on said frame, spring means yieldwill.

ingly supporting the free ends of said arms, a pair of, stems provided with longitudinal slots through which said arms extend re- Y speetively, a second pair of arms pivotally connected to the first pair of arms respectively and having the lower ends of said stems engaged in their free ends respectively, springs encircling said stems and bearing against the first named arms at their upper ends and the second named arms at their lower ends, and circular lmives rotatably mounted on the lower ends of said stems beneath the free ends of the second namedarms respectively.

In testimony' whereof, I aiix my signature, in the presence of two witnesses.
